yacc and pure parsers

[Nhat Minh Le <nhat.minh.le%huoc.org@localhost>]

Hi,

I have not found much about this in the mailing lists, Gnats or the
source code, so I'm asking here (hope this is the right mailing list):
has there been any work in implementing some kind of reentrant parser
generation for yacc(1), similar to GNU Bison's %pure-parser?

Or is there any reason such a feature would not be needed/wanted?
I personally think it's nice since it makes for easier embedding into
other programs and libraries.

Regards,
